Deep Sleep... The default behavior of Mac OS X is to put sleeping computers in 'hardware suspend' mode, during which the RAM is still powered on. This widget allows the computer to enter 'software suspend' mode. Software suspend is a feature similar to what windows call 'hibernation': the computer consumes no power while sleeping, however the wake up process takes more time to complete.

Hibernation is made possible by the Mac OS X Tiger 10.4.3 update. This operating system version is required.

Only the computers with 'safe sleep' feature are officially supported. For now, the only computers with this feature are the more...

  • Changed the authentication method from sudo to Applescript. This should fix the authentication issues under Mac OS X 10.6. Thanks to Oliver Kusche for finding this solution.

Amazing useful app with an unbeatable price ;). Since my Macbook battery is not that good anymore, deep sleep makes transport easy keeping my work fluid.

Deep Sleep 1.2 is a freeware open source DashBoard widget that will transform how you use your desktop Mac. Incidentally with the release of version 1.2 it is now compatible with Mac OS 10.6.x according to the detailed clear user guide. I'm still on 10.5.8, so I can't speak from experience on this. I am using a mid 2007 model of the Mac Mini, and I can now put it into hibernation with one click and with no use of Terminal by me. Hibernation combines the advantages of Safe Sleep with shutting down your Mac i.e. it uses no more electricity than if it was turned off but your currently open applications are exactly as you left them once you awake your desktop Mac with one push of the On/Off button. Entering hibernation takes about 30 seconds---at first it appears to have simply gone into ordinary Safe Sleep as the little LED at the front of the Mac does the usual sleeping slow blinks several times before it goes out. On waking there is no startup clime when you push the On/Off power button, and waking takes roughly 30 seconds or so i.e. much faster than booting up from Off.

Some comments have queried the fact that on the very first occasion you click upon the installed widget it asks for you admin password. Well, I have LittleSnitch installed, and I have not been alerted to any attempts at outboard communication by the widget. Also it is open source so the source code is freely downloadable if you should wish to examine it for any possible naughty aspects.

Note that Deep Sleep will not work with some older models of desktop Macs, see the pdf documention for details.

I can now confirm that Deep Sleep widget v.1.2 works perfectly under Mac OS 10.6.8 which I have been running under on my Mac Mini for about 2 months now.

I WAS going to recommend avoiding this software because of what I thought was a security risk. The way it works is it asks you for an admin password. With that information, it then sets one of its executable files up to have root access to your system. However, since it appears to me the security is set up correctly on that file, it couldn't be modified by malware late r down theroad.

Alas, it hasn't been updated in eons and doesn't work with Snow Leopard as stated.

You can use the following hibernation tool instead. It still works after the security update and doesn't need administrative rights.

I'm still using the older deepsleep app, I don't use widgets.

Since Security Update 2008-005 this application just hangs. I suspect it was depending on some setuid applescript backdoor to work. :p

Would be great if you could choose between this and a smaller design... the full moon is far too big. I got quite a few widgets running and DeepSleep just uses too much space. Other than that a very nice widget. Works fine on Leopard. Got some problems to reach the small "i" sometimes to get to the turn the widget around.

I do not use Widgets - would use if PrefPane or App.

My macbook switched itself (how?) from safesleep to 'Sleep' always shutting down, and when powered on restoring from saved memory. So I set hibernatemode=0 - that just shut down. Now after firmware update hibernate 0 does really sleep, and wakes fast, but still takes 30 seconds to go into sleep, i.e. I suspect it is saving memory to disk even though hibernatemode is 0. Weird?

When I tried this on my MacBook running 10.4.10 it shutdown the computer rather than put it to deep sleep.

I have installed Deep Sleep on my MacBook Intel machine, but whenever I wake it from hibernation the keyboard no longer responds! Trackpad works without problem! Curious if they wil get it to work flawlessly! I would love to use it!

Awesome widget, now I can put my Mac to hibernate when I am sleeping on those long plane flights knowing I won't lose about 10% battery life by the time I reopen it again.
